1 In railroad car journal boxes at present in use,

the inner end of the journal box [5 is open to permit the insertion of the journal l'ithere'through and this inner end of the journal box'is usually provided'with a pocket, as at H, adaptedto receive suitable dust guards illustrated 'at l8. These dust guards generally consist of sheets dust guard receiving pocket. vided at one end with a pair of vertical slits thereor plates provided with a cut out or opening to fit ontothe journal as shown in Figure l and adapted to close theopening l9 about the journal against the ingress of cinders and dirt. After the'dustguards it have been put into place through the open top of the pocket I! and the journal inserted therethrough, the upper end of the pocket H is thenclosed by a suitable key or plugZll generally composed of wood and slightly taperedqtoward bottom to permit the plug to be driven into place; the plug being of length commensurate with the length of the pocket extending transversely of the journal box. The

plugs are intended to'prevent ingress of chieasy application thereof to the journal boxes and l the plugs at the upper ends of receiving pockets.

My improved means, as exemplified. in Figures 1, 2 and 3, consists of a sheet metal'plate 2i shown in perspective inFigure 4, of thickness just sufficient toghave the necessary strength and at the same time enable the body portion of the plate to the dust guard extend vertically in the upper end of the guard pocket intermediate of the closure plug 28' and a wall of the journal box. The plate is of length somewhat greater than the vertical width of the wallsat the inner end of the journal box at the by to provide the two side tongues 23, 23 and the intermediate tongue 2t. The lower end of plate 2i is shown somewhat tapered or reduced into the depending portion 25 and this depending portion bent laterally with the distal end 26 thence curved or bent upwardly as shown in Figure 4.

The device 21 as previously stated is made of bendable sheet metal which permits the tongues 23,. 23 and 2t to be bent laterally after the locking means has been inserted into the plug rev, ceiving end of the dust guard pocket of the journalbox; the device being inserted vbefore the .plug is driven into place.

The plate 2| is pro- ,-In Figures 1 and 2'I show the method of appli- I cation of my improved locking means employed in journal box, the upstanding distal end or lip 26 is then disposed to the outside of the journal box, namely intermediate of the inner end of the journal box and the hub of the wheel (indicated at 21) the tongues 23 preferably are then bent laterally across the top of the plug 20 while the tongue 24 is bent laterally across the top of the outer wall 28 of the journal box and thence downwardly along the outer side thereof as.in-

dicated in Figures 1 and 2.

It is apparent from the construction shown that the laterally disposed portion'of'the lower end 25 with its upstanding lip 26 and' the laterally and downwardly bent tongue 24 will prevent any vertical movement or displacement of the locking means while the laterally disposed tongues 23, 23 will finally lock the plug 29 against upward travel or removal and hence ensure a constant closure for the upper end of the dust guard receiving pocket being maintained;

Where the application of my improved locking means is intended for journal boxes of cars in use, the improved locking means mustbe inserted through the front end of the box provided with the usual lid or closure 29, see Figure 1. To permit such application, the journal box l5 must be jacked up, the wedge block3il and brass 3| then removed thus providing suflicient space above the journal Hi topermit introduction of my locking plate 2| therethrough. In situations of this kindthelocking meansl is inserted upwardly through the plug receiving pocket, with the lower tapered end portion 25, 26 arranged within the journal box as shown in Figure 3 and the laterally disposed portion 25 arranged beneath the shoulders of wall 32 of the journal box. In order to lock the plate in place, certain of the tongues, for example the side tongues 23, are bent laterally across the top of wall 32 of the journal box and thence downwardly against the outer side of the wall 32, thereby firmly holding the locking means in place against movement. The plug 20 is then driven into the upper end of the guard receiving pocket, and the other tongue 24 is then bent laterally across the top of the plug 20 toward the inner end of the journal box,

as shown in Figure 3, thereby firmly locking the plug 20 against any upward movement.

In Figure 5 I illustrate another form of my locking means, namely a type which may be easily applied to the journal boxes without need of jacking up the latter. This type of locking means in its initial form is shown in perspective in Figure 6 in the form of a substantially right angularly bent plate 33 consisting of the upper leg orside 34 and the depending side or leg 35. The upper leg 34 has a partially severed portion which is bent downwardly to provide the depending tongue 36; while the lower end of the depending side or leg 35 is curled or slightly bent in what may be termed an inward direction as shown As this type of locking means is intended to be applied at the ends of the plug 28, a pair are employedas shown in Figure 5 and they may be applied after the dust guard plug 20 has been inserted in place by forcing the tongue 36 downwardly between the end of the plug and the side wall of the journal box; the device being of sheet metal possessing suflicient resiliency to permit it to slightly flex and be sprung about the shoulder or rimof the journal box while the tongue is being inserted. After the tongue 36 has been completely driven into place, the upper side or leg 34 will lie flush with the top of the plug 20, While the curled or bent edge 3'! on the depending or vertical side 35 will snap or extend beneath the rim 38 of the journal box wall. A similar locking device is preferably also applied to the opposite side wall of the journal box, namely at the other end of the plug 20; and in order to ensure against any improper removal of the devices" it is preferred to tack weld the curled edges31 to the side wallsof the journal box as indicated at 38 in Figure 5.

In Figure '7 I disclose another modification of the device. The device 39 is made of sheet metal having a sufficient amount of resiliency to enable the device to be flexed or sprung into place. The

locking means shown in Figures 7 to 9 consists of a preshaped-element with an upper portion 40, and a depending portion 4|, integrally united by the intermediate outwardly bowed or looped portion 42 which enables the required flexing action between the upper portion 40 and the depending portion 4| without undue str'ain'and which also causes the portions 40 and 4| to more or less spring or snap toward each other when the device assumes its final position on a journal box.

The upper side 40 has a partially severed portion which is bent downward to provide the tongue 43 which is intended to be disposed in the plug receiving opening in the journal box as shown in Figure 8 where the tongue 43 is driven between the plug '20 and the rear wall 28 at the top of the journal box, while the main part of side 4|] overlaps the plug. 7

The lower marginal edge of the depending side 4| is bent or curled inwardly, namely toward the side of the device on which top 40 is located, 'as shown at 44. This curled edge 44 is intended to engage beneath the inner or-rear wall 28 of the journal box after the upper part of the" device has been positioned and applied as shown in Figure 8. The resiliency provided by the upwardly disposed loop 42 permits leg or depending portion 4| with its incurled edge 44 to flex outwardly while the tongue 43 is being driven into place and as soon as the upper part 4!! is flush with the top of the plug the curled edge 44 will then be adjacent the lower edge of the journal box "wall 28 and will snap therebeneath, thereby firmly locking the device in place.

With the forms of the device illustrated in Figures 4 and '7, merely one need be employed for each journal box, as these locking devices are preferably located intermediate of the sides of the journal box and hence intermediate of the ends of the plug 2||.- I

It'will be understood, of course, that while the tongues 23, 23. 24 of the device shownin Figure 4 are intended to be bentdown into .place as shown in Figures 1, 2 and 3, the device is made with sufficient rigidity to resist the upward pressure of the plug 20 encountered during car operation. I

The various exempliflcations illustrated in the drawings and described in the specification are believed to be the best embodiments of the invention in connection with car journal boxes as at present employed, but certain modifications are possible and may be made without, however, de-

parting from the spirit of my invention.
